Sd card cannot be accessed by laptop

Much help would be appreciated. Total new experience for me.
I have cm7 stable on sd of my nook color. I have everything up and running great. trying to overclock and when I take my sd card out of nook and put into laptop, it asks me to format it. It is not allowing me to copy the kernal to my sd card. Is there another way of doing this?
While inserted in my laptop, I look at the properties of the sd card and it is showing to be in raw format.
any help would be greatly appreciated.

Are you unmounting the SD card before you eject it? Also, are you sure the FS on your SD is FAT32?

When I originally formatted the card before I burned the installer and the cm file on the card it was formatted to a fat16.
I have not unmounted the card prior to ejecting. I will give that a try.

okay I unmounted before ejecting... put into laptop and the laptop is still wanting to format the card.
when I look at the properties it says file system is raw, and storage space is 0mb.

Maybe your card reader couldn't read microSDHC card?

With CM7 running off a uSD which I am doing as well, some built in laptop readers will not read the uSD but it may be read with a USB reader. But, it will typically only read the 1st partition which is the Boot partition (unless you use a program to set the 4th partition as primary and active).
To access the 4th partition for storage, you can try to connect the Nook by USB cable to your computer and enable USB storage mode. That should connect you to the 4th partition and your internal mmc storage partition too.
If not, download and use the following app:

The app is a little deceiving, you have to scroll in the app to see the "Confirm" button when you are mounting, and unmounting.

Thank you!!! I'm going to try that tomorrow.

If you still have stock on eMMC, boot with the card out, then insert it before the stock OS fully loads (like on "n" or "Nook Color" splash screens). The NC will mount the boot partition as storage; there should be an SD-icon notification in the lower left, and if you tap it, it should say "SD card inserted." You can then connect via USB, and hopefully your card and PC will kiss and make up.
ETA: I've had no luck inserting the card after the OS is fully loaded--it just reads "SD safe to remove."

That worked!!! Thank you very much!!!

[Q] Access to bootable sd card from stock OS after 1.4.1 update

I have a nook color with dual boot from sd card. The sd card having an android 3.0 version.
After I got the 1.4.1 update, I noticed that I was able to access the sd card( the boot partition alone) from the stock OS boot of nook.
But now, dont know how, I dont see that anymore.
Was this a flawed update that was fixed or am I missing something.
Do help please.
I could really use the advantage of using the bootable sd card as a regular storage card when using the stock OS of nook. I prefer reading on the stock OS of nook.

Not sure why you're not seeing the SD card anymore, does it still boot?
SD card installs create multiple partitions on the SD card and the Nook will only be able to access the first one (boot). It should be accessible with any version of the Nook default OS.
You should have a media partition with a decent amount of room (1-5gb depending on NC version). That would give you more room than the 100-or-so mb on the boot partition.
Just found out that you can point the emmc install to see the "sdcard" partition of the sd card using the following info:

Yes, I can boot from it. Every time I plug in the SD card, the notification already says that it is safe to remove the SD card. In the device Info part of the setting, the "Unmount SD card" is already greyed, though it does say that the SD card is found.
It is however useful for me to know that the boot partition should always be accessible.
I did remove the SD card a couple of times without unmounting it first, could this possibly have corrupted the card?

Try to boot the uSD card (the one with Android 3.0 on it) and see what happens.
If it can, then it's good, if not, you can say it's corrupted.

Yes, I can boot from it. So I assume the card is OK
I plugged in other uSD cards and they get recognized fine. So I assume the Nook stock OS device recognition is OK.
I should probably recreate the boot partition as a last ditch effort

I had the same problem at first, but now I have mounted the correct sdcard partition that I wanted to mount.
I couldn't get it to work with editing the vold.fstab file at first. Then at some point after I manually mounted the correct partition through adb shell and edited the vold.fstab it now works.

Nook Glow Internal Files dump

Hi there,
I made a thread here, I bricked my nook because I erased important files without making a backup before.
Someone here in the forums told me to ask for a "nand dump", what is that I'm not too sure but I guess that he meant that I would need the same files that I erased but from someone else and then I should erase some personal data to avoid B&N store account conflicts.
Anyways, I haven't found any dump neither any directions to put it on my nook glow. Does anyone know where could I get such a thing?

I'm stuck like you with a bricked glo-nook, and I haven't heard about that "nand dump".
Could you post again if you learn anything about it?
TIA

If you put noogie on an SD card and boot it it will serve the internal SD card (NAND) over USB.
There should be 7 visible partitions, only the first will get a drive letter in Windows.
Run Win32DiskImager and save that drive letter to a file.
Make sure that the saved result is about 1,9xx,xxx,xxx bytes.

mmmm, in my case I just see a drive letter in W7 and it's the noogie sdcard. No other partitions, Win32DiskImager can't see other partitions either.
But under the portable devices in device administration I can see two devices: boot (drive F:, the noogie sdcard) and G: (can't access)
Thanks for the info.

It sounds like you mashed the partition table on internal SD card.

I don't think I quite understand. If I run Noogie on my SD card then it will boot normally? No matter if I did what I did (erased important files, that's why it's bricked)?

Noogie on an SD card will boot even with the internal SD card vaporized.
This will give you the "Root Forever" screen and serve (whatever exists of) your internal SD card over USB.
Clockwork Recovery on an SD card will boot even with the internal SD card vaporized.
It can perform lots of operation from a menu on the screen.
It can also provide ADB over USB which is helpful for cleaning up stuff.

Alright I will try booting up with Noogie. Thanks for your answers, I just hope I can fix this device.
Thanks again.

Noogie works, I tried to backup the image but I only did that AFTER my Nook had the problem so backing up with Noogie won't do it.
Glownooter WORKS but I don't know what to do to boot it normally. With Noogie I'm stuck on Rooted Forever and while Windows recognizes the nook, it's empty, completely empty.
I don't know what's ADB.

Thanks for clearing that up
But what I'm trying to know is what kind of method will bring my Nook back to life, I'm no expert but I can manage if I'm told at least what will theoretically work.

[Q] Issues with SD Card not mounting on CM10

Hi guys, long time reader and first time poster here with a question. I apologize in advance if this has been asked and answered, but I have searched throughout the nook forums and have not found a solution yet to my problem and any help is greatly appreciated.
I have been wanting to use CM10 as my daily driver on my nook for awhile now, however everytime I flash the ROM and get things set up, I run into an issue where the ROM does not consider my SD card to be mounted. I have adjusted the settings to be set to Mass USB Storage as one person suggested in the development thread, I have formatted it numerous times to try to see if that was causing the issue, and so far nothing has worked.
I know that the SD card that is in my nook is good as it shows up in ICS without any problems. Does anyone else have any idea on what I could try to get the SD card to mount properly in CM10?
Thanks again for any help, and many apologies if this is answered in another thread.

When you say mounted, you mean you cannot see it under storage devices within CM10? It does not show up in your file manager? That USB mass storage setting is just for seeing on your PC when you plug the USB cable in. It has nothing to do with seeing the card in CM10. And you tried formatting several times you said. How did you format it? In the PC with windows? You need to try SDFormatter which is a free windows program on the web. Other users have said that that makes them show up on the Nook. When the nook first starts up, it tries to read the SD and scan it, if it can't, it won't mount it. There could be something very simple wrong with the card that the nook sees and your PC does not.

Leap,
I have to apologize, I used the wrong terminology in my original post. It seems that the issue I am having is with the SD card being stuck in RO mode and not being able to write to it from CM10. Anything that I have tried to download via the Play Store fails to install with an error saying that it could not install to USB Storage or SD Card. I have formatted the card via Windows, CWM, and using the SDFormatter program to no avail. I have also tried to fix permissions via CWM and Rom Manager and that has not resulted in resolving the issue that I seem to be having. I love the speed at which CM10 runs, and if I can get the SD Card to be RW it would easily replace the ICS build that I've been using forever now, I just don't know what else I can try to get the card to be RW while running CM10.

The problem is CM10 is very finicky about the format on the card. If it does not like it, it mounts it read only. Look for SDFormatter on the web and format with that. Should fix it.
Edit, I just reread and said you tried that. That should have fixed it. Do it again but turn off quick format.

Leap,
Thank you for all the help you've provided, however it doesn't seem that doing a long format with overwrite in SD Formatter got it to work. I'm going to retreat back to ICS for now.

Just a question, after you format the card, do you move any files in it? I had the same exact problem and it must have been a defective file in my titanium backup folder because I had no problem using the same sd when I synch'd titanium via dropbox.
I installed the 19/11 nightly and it is better than anything I ever run on nook. even CM7

Tschumi,
After I finish formatting it via SD Formatter, I place it back into the nook completely blank and reboot the nook. After that, I try to download anything from the play store that requires SD install and it fails to install.

Use ROM Manager and select "Format SD card" which will allow apps to install. Nook will reboot into CWM and begin formatting SD card. Be FOREWARNED! You will lose anything you have stored on the SD card so make a backup and trasnsfer to your PC or somewhere you can later retrieve.

Ok so here's an update on this issue for me. It appears that no matter how many times I used SD Formatter to format my 16Gb micro sd card, it would not be recognized by CM10. I grabbed an old 8Gb micro SD card and threw it in my nook and it worked perfectly, so it appears that there's an underlying issue with the card itself that was causing the problems. Thanks to everyone for the tips and advice on how to fix this issue for me. I appreciate it.

I am having the same issue with my 16GB Patriot microSD card. The card is recognized, but always displays as full (26GB used) in the settings menu. I have reformatted numerous times to no avail. I have an old 4GB card in there now with no issues.

It is that Patriot brand and CM10. CM10 is very finicky about sdcards. If it does not like how one performs, it changes it to read only. You can try formatting the card with SDFormatter, which you can get free on the web. That may help, but it may not.

[Q] SD card partition problem

So I am running CM7 off of an sd card in my nook color.(Using http://forum.xda-developers.com/showthread.php?t=1904129 and I highly recommend). Win32discimager for some reason created a small partition just larger than the installer which remains on the card. I also have the android OS on the card that is taking up 1 gb partition. The rest of my 16gb micro sd card is labeled as the emmc for the tablet which is not what i intended. Now I cant load it up with my movies and videos like I had hoped.
Does anyone know:
Is there any way I can change these partitions on my card? (I have already tried EasuUS partition manager)
Where did the 1gb partition that android is on come from and why did the emmc get so large?
Is there any way to take the android image currently on my sd card and just putting onto the nook after I have already had it run from the sd card and then just formatting my sd card for storage?
There are probably newbie questions but I have tried to do my own research and havent found any certainties. Any help would be really appreciated.

Ok, first you need to go to my tips thread linked in my signature and read in section B how the verygreen SD works. You will understand the partition structure a little better.
Now for your sdcard/emmc media storage problem, you have a setting wrong in CM7. Go to settings, CyanogenMod settings, Application and uncheck "Use internal storage". What that setting does is swap emmc and sdcard so that your real sdcard is called emmc and internal media storage is called sdcard. It is not default that way. Somehow it got checked.
